don't worry I know what to expect on a first release (especially on an indie one). Though you shouldv'e just named it as beta version with a version number less than 1 since it still has missing parts and IS still a test release.

actually there is something like this but isn't a turret but still fires projectiles. I saw it in CODMW2 on their amphibious vehicle things. It fires spread bullets like a shotgun and it would fire whenever it detects a missile in close proximity. Don't know how you can implement it on the vehicle though. :\

I've been wondering... Because there isn't any special lighting effects in this game (yet) can you simulate a shadow effect on the tank texture? I wanted to try it but lost motivation =(
I think you should just put gradient on the parts were light can't reach that face such as the undersides of the tanks or something
